Welcome to the Walker River Basin Hydro Mapper. This mapping application provides a basin-wide perspective of real-time streamflow and lake and reservoir storage capacity and stage for the Walker River Basin in Nevada and California. The Hydro Mapper also provides access to historic streamflow, and lake and reservoir data. This tool was developed to create a common operating picture for water users in the Walker Basin and to help monitor changes to instream flows associated with the Walker Basin Restoration Program.

The Walker Basin Restoration Program was enacted by Congress in 2009 through Public Law 111-85 and is administered by the National Fish and Wildlife Foundation (NFWF) through the Bureau of Reclamation's (BOR) Desert Terminal Lakes Program. The program's core purpose is to restore and maintain Walker Lake, a natural, terminal lake in west-central Nevada at the endpoint of the Walker River system of Nevada and California. Walker Lake is an internationally protected stopover point for migratory birds on the Pacific Flyway and an important fishery for threatened Lahontan cutthroat trout. Depleted freshwater inflows and changes to the hydrologic cycle have resulted in declines in lake levels and increases in salinity which threaten the ecological health of the lake.
